T1204.002 Malicious Link
The PDF contains numerous links to external websites, many of which are structured as SEO-optimized links for game-related hacks and free items. The ML classifier strongly indicated maliciousness, and the presence of a 'download button' heuristic further supports a malicious intent to trick users into visiting potentially harmful sites. The primary attack pattern involves luring users with promises of in-game advantages.
